Referring now to FIGS. 1-8, reference numeral 10 generally designates a rearview device having a housing 12 that includes a first side 14 and a second side 16 opposite the first side 14. An electro-optic element 18 is operably coupled with the first side 14 of the housing 12. A rear trim bezel 20 is disposed on the second side 16 of the housing 12. A rear trim plate 22 is operably coupled with the second side 16 of the housing 12. A peripheral gap 24 is defined between the rear trim plate 22 and the second side 16 of the housing 12. A spacing truss 26 is disposed in the peripheral gap 24. The spacing truss 26 includes first and second lateral walls 30, 32 extending to the rear trim bezel 20.

Referring now to the embodiment depicted in FIGS. 1, 2, and 8, the rearview device 10 includes the electro-optic element 18. A first substantially transparent substrate 40 includes first and second surfaces 42, 44 (FIG. 9) disposed on opposite sides thereof. The second surface 44 includes a first electrically conductive layer 48. A second substantially transparent substrate 50 includes third and fourth surfaces 52, 54 disposed on opposite sides thereof. The third surface 52 includes a second electrically conductive layer 56. An electro-optic medium 60 is disposed in a cavity 62 between the first substantially transparent substrate 40 and the second substantially transparent substrate 50. The electro-optic medium 60 is variably transmissive such that the electro-optic medium 60 is operable between generally clear and darkened states. A display device may be disposed proximate the electro-optic element 18.

Referring again to FIGS. 1-3, the rearview device 10 generally includes a mounting assembly 90 having a mount 92 configured to engage a windshield button. The windshield button may be generally secured via an adhesive or other method of connection to a windshield of a vehicle. The mount 92 includes a base 94 and a mount ball 96 that projects from the base 94 and is received by a mount barrel 98. The mount barrel 98 engages the mount ball 96 of the mount 92, as well as a device ball 100 (FIG. 4) that is operably coupled with a rear portion 102 of the rearview device 10. The device ball 100 includes an engagement portion 104 configured to be secured with a mounting area 105 of the rear trim plate 22 of the rearview device 10 includes a receiving member (socket). It will also be understood that the mounting assembly 90 may be a single ball mount in which the rear portion 102 of the rearview device 10 directly engages the mount ball 96 of the mount 92.

With reference again to FIGS. 1, 2, 4, and 6, the rearview device 10 includes an ambient light sensor 110 that receives light through an aperture 112 that extends through the rear trim plate 22. The rear trim plate 22 includes an intermediate portion 114 and a peripheral flange 116. The peripheral flange 116 extends around the intermediate portion 114. The intermediate portion 114 also includes aesthetic portions 118 that are generally disposed on first and second sides 120, 122 of the device ball 100. In FIGS. 1 and 2, the housing 12 extends from the rear portion 102 of the rearview device 10 to a forward portion 121 (FIG. 5) of the rearview device 10, and includes a front recess 123 (FIGS. 8 and 9) configured to receive the electro-optic element 18. It will generally be understood that the electro-optic element 18 could be replaced with a prism-type element or other display-type element suitable for use in providing a rear view to an occupant in a vehicle. Because the housing 12 extends around and receives the electro-optic element 18, the rearview device 10 is free of a separate peripheral bezel. However, as previously noted, the rearview device 10 does include a rear trim bezel 20 that is visible from a rear side of the housing 12. Notably, the rear trim bezel 20 is not generally visible from a front of the housing 12 along a line of sight perpendicular to the planar extent of the electro-optic element 18.

The housing 12 generally includes a plurality of rounded corners 130 that may be generally complementary in shape to rounded corners 132 of the electro-optic element 18. In addition, a badge 136 is positioned over a top forward edge 138 of the housing 12 and the first surface 42 of the electro-optic element 18. It is generally contemplated that the badge 136 will be configured to display a purchaser's trademark, logo, etc.

Turning now to FIGS. 3 and 4, the juxtaposition of the rear trim bezel 20 is readily discernible. In addition, the peripheral gap 24 (FIG. 9) that is defined between the rear trim plate 22 and the second or rear side 16 of the housing 12 can be seen. As illustrated, the peripheral flange 116 of the rear trim plate 22 is angled in a direction toward a peripheral edge 140 of the housing 12. Thus, the peripheral flange 116 of the rear trim plate 22 is not coplanar with the planar extent of the intermediate portion 114 of the rear trim plate 22. It is also contemplated that the rear trim plate 22 may include a curvilinear architecture. Regardless, it is generally contemplated that the peripheral flange 116 will extend toward and be angled toward the peripheral edge 140 of the housing 12. Nevertheless, it is also contemplated that the peripheral flange 116 could also extend linearly generally parallel with the planar extent of the electro-optic element 18.

With reference to FIGS. 5-7, the rear portion 102 of the rearview device 10 includes a generally curved design. An aesthetic channel 144 is disposed between the intermediate portion 114 and the peripheral flange 116 of the rear trim plate 22. In the illustrated embodiment, first and second spacing trusses 26 are located on each side of the rearview device 10. The first and second spacing trusses 26 are shown extending in a direction toward the plurality of rounded corners 130 of the housing 12. Each of the first and second spacing trusses 26 includes a base wall 131 from which the first and second lateral walls 30, 32 extend toward the rear trim bezel 20. In the illustrated embodiment, the first and second lateral walls 30, 32 of the spacing truss 26 terminate at the rear trim bezel 20. However, it is generally contemplated that the first and second lateral walls 30, 32 may extend past the rear trim bezel 20, or may terminate before reaching the rear trim bezel 20. In addition, the first and second lateral walls 30, 32 are set at angles relative to the linear extent of the rearview device 10. Stated differently, the first and second lateral walls 30, 32 are not parallel. Rather, the first and second lateral walls 30, 32 extend at an angle relative to one another, generally in the direction of the plurality of rounded corners 130 of the housing 12.

With reference now to FIGS. 3 and 7-9, the components of the rearview device 10 as set forth in FIGS. 5 and 6 are illustrated in an exploded view. The housing 12 is configured to receive a washer 150 that supports and receives fasteners that secure the device ball 100 to the rear side or second side 16 of the housing 12. The electro-optic element 18 is received in the front recess 123 (FIG. 8) of the housing 12 and the badge 136 is secured to the first surface 42 (FIG. 9) of the electro-optic element 18. The badge 136 may be coupled with the housing 12 or the electro-optic element 18 via mechanical fasteners, adhesive, etc. In addition, the rear trim bezel 20 is generally illustrated, which is configured to engage the second side 16 of the housing 12. The rear trim bezel 20 extends around a periphery of the housing 12 on the second side 16 of the housing 12. However, the rear trim bezel 20 does not extend around the peripheral edge 140 of the housing 12. In addition, the spacing trusses 26 are operably coupled with the second side 16 of the housing 12, and include engagement flanges 156 protruding from an engagement side 158 of each of the first and second lateral walls 30, 32, which engage receiving slots 160 defined on the second side 16 of the housing 12. It is generally contemplated that the flanges 156 may engage via a snap-fit connection, for example.

With reference again to FIGS. 7 and 8, the rear trim plate 22 extends over a body 161 protruding from the housing 12. The body 161 generally defines a cavity 162 configured to house a printed circuit board 163. The body 161 includes a peripheral wall 164 that is generally parallel with a planar extent of the eletro-optic element 18. The peripheral wall 164 extends outwardly from the body 161. However, the rear trim plate 22 extends primarily over a rear face 166 of the body 161. A rear applique 170 is configured to engage a rear portion of the housing 12. The rear applique 170 defines an inner opening 171 within which the rear trim plate 22 and the mount 92 (FIG. 3) extend to couple with a rear portion of the housing 12. Thus, the rear applique 170 extends around the mount 92 and the rear trim plate 22. In addition, left-hand and right-hand appliques 172, 174, are configured to engage recesses 173 of the housing 12 disposed on left and right sides of the mounting area 105 (FIG. 1) of the device ball 100, respectively. As with the badge 136, which may include a variety of different emblems, logos, trademarks, etc., the appliques 170, 172, 174 are generally configured to be interchangeable to accommodate the needs of a particular purchaser. In addition, the appliques may be decorative appliques that match the interior or trim of a vehicle.

With reference now to FIGS. 8 and 9, the peripheral gap 24 defined between the rear trim plate 22 and the second side 16 or rear side of the housing 12 is illustrated. The rear applique 170 extends generally from the rear trim bezel 20 all the way to the body 161 of the housing 12. In addition, the rear applique 170 is larger on the sides than on the top and bottom. Further, it is generally understood that the peripheral wall 164 includes a bulbous rim 180 that extends about the periphery of the housing 12. The bulbous rim 180 is configured to conceal at least a portion of the periphery of the rear trim bezel 20, as well as the periphery of the electro-optic element 18. In the illustrated embodiment, the bulbous rim 180 generally abuts and conceals an outer wall 182 of the rear trim bezel 20. Further, the electro-optic element 18 is generally set in the front recess 123 such that the bulbous rim 180 protrudes slightly beyond the first surface 42 of the electro-optic element 18.

Turning again to FIG. 8, in the illustrated embodiment, it is noted that the intermediate portion 114 of the rear trim plate 22 is not coplanar with the peripheral flange 116. Further, the peripheral flange 116 may be constructed from a different material than the intermediate portion 114 and optionally include different reflective properties. In addition, the housing 12 supports the printed circuit board 163 illustrated as including a glare sensor 192 that receives light directed at the electro-optic element 18. The glare sensor 192 includes a light pipe 194 that conveys light directed at the electro-optic element 18 from the first surface 42 of the electro-optic element 18 to a rearward side 196 of the printed circuit board 163. Thus, a sleeker and slimmer profile from front to back can be obtained on the rearview device 10, as illustrated. In addition, the peripheral wall 164 includes a planar extent that is generally parallel with a planar extent of the electro-optic element 18. Accordingly, the printed circuit board 163 and other circuitry, as well as any other components that are made available for the rearview device 10, are all provided in the body 161 of the housing 12 and do not extend as far as the peripheral walls 164 of the rearview device 10. However, it is contemplated that in some embodiments, additional room may be gained between the electro-optic element 18 and the peripheral wall 164 of the housing 12.

The multi-piece construction, as set forth above, includes improved aesthetics that are configurable to provide multiple styling options. Various appliques can be changed to modify the appearance of the rearview device 10. In addition, the spacing trusses 26 are plated and can be removed to modify the appearance of the rearview device 10. Further, the rear trim bezel 20 can be modified to include different finishes, thus also modifying the appearance of the rearview device 10. The rear trim plate 22 gives the appearance of having a floating condition. In one example, the outer portion or peripheral flange 116 of the rear trim plate 22 is clear, while the intermediate portion 114 is opaque. In another example, the peripheral flange 116 is opaque, while the intermediate portion 114 is clear. Variations on this configuration can be made to provide various aesthetics, depending on the preference of the consumer. Moreover, the rear trim plate 22 provides an aperture, as set forth above, that allows for the ambient light sensor 110, which is located in the body 161 of the housing 12, to receive light, thus providing data to the printed circuit board 163 related to the ambient light condition when the vehicle, and specifically the rearview device 10, are being used.

The electro-optic element 18 could also be an element such as a prism. One non-limiting example of an electro-optic element includes an electrochromic medium, which includes at least one solvent, at least one anodic material, and at least one cathodic material. Typically, both of the anodic and cathodic materials are electroactive and at least one of them is electrochromic. It will be understood that regardless of its ordinary meaning, the term “electroactive” will be defined herein as a material that undergoes a modification in its oxidation state upon exposure to a particular electrical potential difference. Additionally, it will be understood that the term “electrochromic” will be defined herein, regardless of its ordinary meaning, as a material that exhibits a change in its extinction coefficient at one or more wavelengths upon exposure to a particular electrical potential difference. Electrochromic components, as described herein, include materials whose color or opacity are affected by electric current, such that when an electrical current is applied to the material, the color or opacity change from a first phase to a second phase. The electrochromic component may be a single-layer, single-phase component, multi-layer component, or multi-phase component, as described in U.S. Pat. No. 5,928,572 entitled “Electrochromic Layer And Devices Comprising Same,” U.S. Pat. No. 5,998,617 entitled “Electrochromic Compounds,” U.S. Pat. No. 6,020,987 entitled “Electrochromic Medium Capable Of Producing A Pre-selected Color,” U.S. Pat. No. 6,037,471 entitled “Electrochromic Compounds,” U.S. Pat. No. 6,141,137 entitled “Electrochromic Media For Producing A Pre-selected Color,” U.S. Pat. No. 6,241,916 entitled “Electrochromic System,” U.S. Pat.

The glass element may also be any other element having partially reflective, partially transmissive properties. To provide electric current to the glass element, electrical elements are provided on opposing sides of the element, to generate an electrical potential therebetween. Element clips, such as J-clips, are electrically engaged with each electrical element, and element wires extend from the J-clips to the main printed circuit board (PCB).

The present disclosure may be used with a rearview assembly such as that described in U.S. Pat. Nos. 8,925,891; 8,814,373; 8,201,800; and 8,210,695; U.S. Patent Application Publication Nos. 2014/0063630 and 2012/0327234; and U.S. Provisional Patent Application Nos. 61/709,716; 61/707,676; and 61/704,869, which are hereby incorporated herein by reference in their entirety.
